Check on ebay, for the japanese version of the ring (ringu), and get ringu 2, and ringu 0. It's the sequel, and prequel to the ringu. Ringu is basically the exact same thing with the ring, except it'll make you jump and give goose bumps on other scenes.
Part 2 is about the same level as the original, but 0 is scarier.
the ring is a rip off, from Japanese psychotic, yet genius minds.
